The anti-feeding effect of different extracts derived from three moss species (Atrichum undulatum, Kindbergia praelonga and Hypnum cupressiforme) against Burgundy snail (Helix pomatia)

Abstract

The anti-feeding effects of extracts from three bryophyte species, namely Atrichum undulatum (Polytrichaceae), Kindbergia praelonga (Brachytheciaceae), and Hypnum cupressiforme (Hypnaceae) were evaluated against Burgundy snails (Helix pomatia) under laboratory conditions. Ethanol, methanol, and dimethyl sulfoxide (DMSO) extracts and water decoction were used in four concentrations (1%, 3%, 5%, and 10% aqueous solutions). All the tested extracts demonstrated a certain level of anti-feeding effect. A positive relationship between extract concentration and anti-feeding effect was observed particularly for ethanol extracts of A. undulatum. Methanol extracts generally exhibited the weakest anti-feeding effects, except for H. cupressiforme, where the ethanol extracts showed the weakest performance. The potential of different bryophyte extracts as biocontrol agents is discussed.
